Referring now in detailtothe drawings, ,an 5

automotive Vehicle such as a motor truck is indicated at 10. The'usual constructionof vehicles of' thistype includes a pair Aof chassis rails 11,

Vwhich'aregenerally steel channels having such,t 'detailed construction as the design ofthe vehicles l0 mayy require.l 4The railshll are generally connected bycross members suchV as 12 and a tail piece13.V l f "Atilting body forthe vehicle is indicated at 14W f' and' comprises a frame indicated generally at 1 5."'15 a fioor1d`s'idewalls 17, an end wall', 18, and a tailgate 19. The frame 15 rests, on sills20 A"clampedwto the rails 11 of the vehicle chassis. Theframe is pivoted on thesefsills' by meansI of a pivotshaftf21for tilting movement to? thev posi- 20 tion-indicated! in Figure 1 in chain'lines, vunder 'the influence of the force exerted 'by a hydraulic jack 22. "The details of the jackand its connection"to k`the Vbodyland frame co'nstitutefno part of the present invention butl are'fully disc1osed'25 yand claimed in my copending applications,V Serial Nos.'257,707`and 411,777. As is usual irl-*devices 'of the general type under discussion, a uid pump 'drivenV 'fromN aV povv'er4 take-ofi onv the truckv trans- Y *mission is provided 'and a valve is employed for 30 vcontrolling the supply of fluid from the pump to ythe jack and the exhaust of fluid fromV the latter.

Referring novvY more'partic'ularly to Figures '3 through' 6,V the ldei'fa'ils of the body constructionn and Vmounting vvillV now be described. The sills35 20 comprise a Wooden core -20 covered on three Psides by a sheet metalfshell'23. The sills rest onthe upper ange 24. ofthe rails 11 andare "secured thereto 'by`means presently to be de-n V'scr'ilciedL Y `40 rvThe pivot 'shaft21"for tiltably supporting the body 14 von the sills 20 extends across the chassis,

'traverses'thesills 20 and extends therebeyond.

Between the tsills 20, the Yshaft 21'is surroundedv by 'alsleeve' 25,'the Vends of which are provided'li withV a straight thread.v vThrust plates 26 are positioned between the endsr of the sleeve 25 'and the metal sheathing 23 of the sill 20.

AAn eyeebolt 27 isl threaded on each end of the sleeveV 25 'Y and is adjusted thereon until the 50 sha'rik of the' boltengagesthe edge of the up- V per flange 2e of the railr channel. The sills'n20 are thus laterally positioned with respect to the "railsandare prevented fromy shifting in eitherQT "lsirettion', Nclamp -28 consisting of a rightan- 55 gle bracket has a hole 29 for the passageway of the eye-bolt 27. One end of the clamp is adapted, as shown at 30, for engagement with the under surface of the top flange 24 of the rail 11. The other end of the clamp, as shown at 31, is bifurcated to form a yokeadapted to engage the sleeve 25 surrounding the shaft 21.

As a result of the construction just described, it is possible to clamp the sills 20 firmly to the rails 11 without the necessity of drilling the rails or making other preparations whichl consume time and labor. As before stated, the position of the eye-bolt 27 on the threaded ends of the sleeve 25 determine the position vof Ythe sills with respect to the rails 11 and prevent lateral displacement thereof. When 'the clamps 28 are placed in position and tightened up by means of nuts 32 on the eye-bolts 27, the sills 20 are drawn rmly against the top flange of the rails and are rigidly secured thereto.

Y, The forward ends of the sills 20 are secured to the rails 11 by meanssimilar to that Ljust described for the rear endsthereof. A diaphragm 33 traverses the sills 20 adjacent their forward ends and has end flanges for bolting thereto.

, By means of bolts 34 welded to the diaphragm,

and clamps 35, similar to those shown at 28, the forward ends of the sills are secured tightly to the top flange of the rails.` vThe sills are also braced by a diaphragm similar to 33, shown at 33 located about midwayvof their length. These diaphragms are vomitted` from Figure 4Vfor the sake of Vclearness. Y

`The body 14, which is mounted on the shaft 21 for tilting with respectto the sills 20, `comprises a pair of longitudinal members 3,6 Ywhich preferably take the form of angle bars having one -flange 37 disposed vertically and'another ange k38 disposed horizontally. VThe liange 37 may conveniently be tapered from the rear end of the body tothe front thereof and may have itsr edge rolled slightly as at 39 for a purpose to appear later. Adjacent the front and rear ends of the members 36, and transversely thereof,ropen bottomed'box girders 40 are positioned. The lower edges of the girders are turned outward to form :danges 41 which provide awidebearing surfaceV for the girders on the members 36. At the front and rear ends of the-members 36, channel 42 and Z-bar 43 are disposed;V The girders, channel and-Z-bar are preferably weldedto the longi- V tudinal members. j

The ends of the `girders extend beyond the members 36 and are out on a bias to the length of the girder as indicated at 44. The open ends'V of Vthe girders are covered by box closers 45 which are simply hollow members formed from a roughly triangular sheet of metal of dimensions such that they are adapted to slide into the open ends of the girders 44. The closers 45 are welded to the ends of the girders, and they are designedgso that their inner and lower. ends extend downwardly below the bottom vedges of the girders and engage the vertical flanges of the members 36. At this point, the closers are welded to the side flanges of the longitudinal y members.

Auxiliary longitudinal 'members 46 comprising Z-bars are disposed between the inner flanges of the girders 40 and'within the. sills 20 and the longitudinal members 36. VShort girders 47 extend transversely between the Z-bars 46 and A the longitudinal members 36 at points intermediate the girders 40. The short girders 47 correspond exactly in shape and. construction to gidity.

the end portions of the girders 40 and have box closers 48 welded thereto and extending downwardly to engage the vertical flange 37 of the members 36. Y

It will be apparent from the foregoing that the body oor 16 is thus provided with proper support at all points thereof. The floor, of course, rests on the channels 42 and 43, the girders 40 and 47, and the Z-bars 46 and is welded thereto at frequent intervals. The construction is such thatrthe entire body, while made up of members formedfrom comparatively thin plates, is characterized by the utmost strength and ri- The girders 40 and 47 afford ample support for the Alcentral'portion of the body floor together with the Z-bars 46 and the closers45 and 48 provide substantial bracing for the edge portions of the floor and the ends of the girders to which they are connected. The construction is simple and relatively inexpensive. Another advantage is that the central'portion of the under frame of the body defined by the girders 40 and the Z-bars 46 provides an admirable.. space for the jack 22 and the mechanism by which it is connected to the body, as'

ably mounted onithe sills 20 by means of the4 pivot shaft 21. The details kof the pivotal support will now be described. As shown in Figure 3, the shaft 21 extends through the vertical flange of the longitudinal members 36. The box closers 49 for the rear girder 40 differ from the other closers slightly in that their Alower ends are sheared off at an angle, las shown at 50. Through the opening thusformed, a bearing box or housing'51 extends upwardly from the lower edge of the flange 37. The bearing-box 51 may conveniently take the form of a metal sheet formed up intolbox shape. The box is welded to the flange 37 of the member 36 and to the lower cropped edgeof the closure 49. Alined bearing openings are formed in the flange 37fin the` member 36 and the outer wall vof the box 51. A bearing 52 is seated in these openings and is welded at 53 to the flange 37 and the wall of the box 51.v Within the bearing 52,

a bushing 54 receives the end of the shaft 21.`

invention is characterized by numerous advan-` tages. Several of these have already been mentioned. In addition to the strength and rigidity imparted to the under frame of the body by the construction employed, another particular advantage results from the arrangement of the longitudinal members 36 relative to the sills 20. It will be seen in lFigure 3 that when the body is lowered the members 36 have their flanges disposed in close relation to the outer and top surfacesof the sills 20. The weight of the body and its load is thus carried directly on the sills 20 and is transmitted therethrough to the vehiclev chassis rails 11. The vertical ange of the members 36 is rolled or beaded as at 39, as previously stated,so that when the body is raised while the vehicle is standing on unlevel ground, if the body and chassis are warped or twisted slightly from their normal relation, the lower edge of the flanges 37 will engage the outer surfaces of the sills 20 on lowering of the body, to guide the latter into its proper relation with the sills when in lowered position.

By employing Welded construction throughout, I simplifythe manufacture of bodies and reduce the cost thereof. At the same time, strength and rigidity are not sacrificed but the resulting construction is amply strong and rigid for the requirements of any class of surface. The entire superstructure, including the sills and body, is rmly fixed relative to the chassis rails without necessitating any extensive work on the latter. The bearing construction by which the body is tiltable on the supporting sills is Very simple and formed entirely of Welded sheet metal parts. At the same time, it affords ample bearing surface and meets practical requirements in an eminently satisfactory manner.

Certain details such as those of the body walls, tail gate, and lifting jack have not been described since they constitute no part of the present invention.

Although I have illustrated and described one specic embodiment of my invention, it is to be understood that this embodiment is merely illustrative as it shows only one preferred form. Since the invention may be otherwiseembodied, it is not to be limited by the disclosure or otherwise, except by the scope of the appended claims.
